Also the resistor for the I/V needs to be > 150R or I have found that THD+N starts to rise to unacceptable (to me) levels. So if your using the SE output, its better to do it as I described. Cheers!

You can get slightly better DNR by decreasing the gain of the first stage and increasing the gain of the second, but I liked the way the stock configuration sounds, so that's the way it comes. :)
